Abstract : The study was initiated to determine the influence of an underlying rock interface on the response of buried cylinders to blast loading. Static and dynamic tests were conducted on eight different 6-inch-diameter steel cylinders buried horizontally in a dense, dry sand. The major variables were the cylinder thickness and the location concrete bottom. Measurements were made of hoop strain, vertical diameter changes, and accelerations of the cylinder; free-field stress, strain, and acceleration of the soil; and surface overpressure.
